Adolescence (ages 10-24) is characterized by cognitive, behavioural and social development. Childhood environments are typically centred on home and care settings, whereas adolescents increasingly engage with peer and community environments. These changing environments confer risks of experiencing specific adversities at different ages. Despite the unique characteristics of adversities in adolescence and potential associations with lifespan outcomes, few frameworks exist to systematize adversities in adolescents. Here we review current research and propose an approach specific to this developmental period: the adverse adolescent experiences (AAEs) framework. Building on existing models (for example, the adverse childhood experiences framework), the AAEs focus on potentially traumatizing experiences during adolescence. The framework builds on Bronfenbrenner's ecological systems theory to conceptualize adversities at intrapersonal, interpersonal, community and societal levels. We argue that this approach can enhance our understanding of adolescent adversity, facilitate the study of its potential effects, and guide prevention and intervention efforts.
